RlVETlN G-MACHINE.

SPECIFICATION forming part of Letters Patent No. 543,324, dated July 23,1895.

Application filed March 23, 1893. Serial No. 467,269. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL M. VAUOLAIN, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented an ImprovedRiveting-Machine, of which the following is a specification.

The object of my invention is to so construct a riveting-machine that alocomotiveboiler can be riveted entirely by the machine as closetogether as possible, as shown by dotted lines in' Fig. 1, and theriveting-head is usually made fiat on top and the boiler is hung .insuch a manner that the fire-box section will swing over the head Binstead of under it, as shown in the drawings. This arrangementnecessitates the readjustment of the boiler in many cases three or fourtimes, and then a number of the rivets have to be headed by hand. Thehanging of the boiler with the fire-box uppermost prevents the operatorseeing the greater portion of the rivets, as they are adjusted andriveted without stooping,

'and consequently several of the rivets are headed at random.

By my invention the boiler can be suspended as shown in Fig. 2, andevery rivet in the trunk portion as well as the fire-boz'c portion canbe seen by the operator and can be properlyriveted without readjustment.

A is a standard secured to another standard B by tie-bolts c. Aspacing-block O is placed between the two standards at the base so as togive sufficient space for the article to be riveted to swingjin. Thelower portions of the standards are mounted in a suitable foundation,asshown in Fig. 1'.

Secured to the plate or. of the standard A is the riveting-head 'D, theportion D of whichprojects over the space between the two stand havingsuitable pipes and connections at-,

tached to the pressure mechanism; but it will be understood thatmechanical riveting mechanism may be used without departing from myinvention.

The anvil bis secured to the standardB in any suitable manner and inline with the plunger 61.

-As shown in Fig. 2, the locomotive-boiler is arrangedin position sothat the riveter can rivet the joint between the fire-box and the trunkof the boiler, the fire-box section being in the space under theoverhanging portion D of the head and between the two standards A and B.By hanging the boiler in this manner the operator can see every rivet asit is headed without stooping. Consequently the rivets can be placed inposition more quickly and the head of each rivet properly made.

I do not wish to limit myself to the construction ofthe lower portionof" theriveter, as shown in the drawings, as this construction may bemodified without departing from my invention.

I claim as my invention- The combination of the standards'A and Barranged a distance apart to allow the fire box of a locomotive boilerto swing between them, a spacing block 0 mounted between the standards,a bolt. securing the standards together, an anvil on the standard 13, ariveting head D on the standard A and overhanging the space between thestandards A and B to a point near the anvil, riveting mechanism in saidhead, the overhanging portion ofthe head being fiat on the under side,substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

SAMUEL M. VAUOLAIN.
